Specification of Letters Patent.

Patented April 2, 1907.

Application filed April 17,1908. Serial No. 312,100-

new and useful Improvements in Windmills,

of which the following is a specification.

This invention relates particularly to that type of windmills which are provided with mechanism for converting the rotary motion of the wheel into'a reciprocating motion to operate or actuate a pump-rod; and the present invention has for its object to improve the general construction of the support for r 5 the wheel, the turn-table, the means for placing the blades of the wheel in different posi tions, and the connectionsbetween the pum' rod and shaft of the wind-wheel, as will .e hereinafter set forth, and specifically pointed out in the several claims.

in the accompanying drawin s, Fi 'ure 1 is a vertical section of a windmil me e in accord with my invention, and Fig. 2 is a detail view showing connections between the driven chains and t e pump-rod.

' instead of providing the usual built-up tower to support the wheel and its platform such parts are carried by a tubular column A, and to said column there is secured a plat- 0 form A, guy-rods a a being secured to the platform, so as to brace the support. The platform has an opening therethrcugh for the passa e of the lower wheel-supporting sec-- tion 1*, and above the platform near the upper end of the tubular standard or column there is secured a casting or fiXture'B, such lhtture having} a vertical opening therethrough for assage of the upper section of the head a' ange on such head resting o on ball-bearingsseated in a recess, so that tney will impinge against the flange and the .side of the tubular ortion of the head which is passed through tli fixture. Below the latform there is secured 5 a casting or fixture the o ning'to one side of the support A being sma er thanthe open ing through the upper fixture B. "IThis loser fixture has a ball-race and an opening for the passage of a bar C, that is also ided by an 5o apertured stud which is secure to the support, the eye through the stud c bein on a line witl. the smaller 0 ening through t e fixture C. The vertica l'y-maintained bar C" has fastened thereto an arm 0 to engage a slide on theI'puInp-rod U the slidejbeing guide-sprockets l) baa e'circular opening of the connected to a weighted bell-crank lever for moving another slide to place the blades of the wind-wheel in different positions.

The uppersection of'the wind-Wheel support or its head D has below the flanged a tu- 6o )ular depending part D, that passes through the larger 0 enin of the fixture B, and below the undhr side of the fixture are boltholes for the reception of bolts which connect an intermediate sectionhl to the head. l

The head D is constructed to provide bear? lugs for the shaft D, which carries the wheel 41 and a slide 03, which is moved upon the shaft D by a lever that is pivoted to an arm e, attached to.the head, the longer end of the arm carrying a weight, the tendency of the wei ht being to lower the long end of the le= vcr e and move the slide forward and turn cranlcrods which are connected to the blades of the whee The lever e has attached 7 5 thereto a flexible connection which passes over a guide-pulley on the upper end ofan arm 6, the lower end of the connection being attached to the-upper end of a' rod C) the i lower end of the rod. being fastened to the So slide that is engaged by the arm 0, and by drawing down on the bar 0 the armc may be moved to render the wheel idle. It will be noted that the rod 0 passes through the hollow sections of the wheel-support. In

line with the shaft D is a stub-shaft 'D,--

such shaft and the wheehcarryihg shaft Di." having fast thereon betweenthe hearings spur-gears that meshwith' gearson the ends of a shaft (i so that t' i unison, and the adj a' D and I) carry sprf which pass chains .d

I supported by an inte section E atop osite form bealings af dr :the ub shafts '3 near the upper-and. lower ends ef the intermediate sectionor connection cal'slo'ts m fitjtlirough'which pass o sat I which connttthe intermediate section E to the lower portionof the upper section or head Band to the upper part of the lower section 9 F, so that the three sections will be connected" I to turn in unison, the central section being su ported by the chains (1 d Each chain (1 has a link constructed to carry one end of a shaft or cross-bar g, to which is connected a pitman G. The pit-man G has therethrough a slot in which is pivoted a cross-head G, the I re the guide-sprockets 'eing carried by the ends of the lateiallyprojecting upper part of the cross-head engaging recessed guidebars h h, which are carried by the head or upper section D and by the intermediate or suspended section E. The lower ends of the recessed guide-bars it h are bolted directly to the intermediate section E, and the upper ends of the bars have therethrougrh slots for the passage of bolts h. The slots permit vertical move ment of the section E, and. the pivoted crosshead G insures a steady movement of the pitman and prevents the chains being twisted or thrown out of alinernent with the sprockets over which the chains pass.

The lower section of' the whe'ehsupport is connected to the intermediatesection E, and

the lower section F has a reduced lower portion that passes "through the fixture the shoulder f resting on "the ball-bearings f. The pump-r0d C is connected to the pitman G by a suitable coupling that permits the rod to turn in the coupling.

It will be noted that the wheel-support herein shown provides an elongated head which incloses the transmitting mechanism and that the parts are connected to, be sub.

.stantially selfadjusting. The chains are kept tautby the weight of the intermediate section, and the pivoted. cross-head overcomes irregularity of movement and jar incident to the change of direction of movement of the pitman in passing the sprockets. 3

Having thus set forth my invention, what I claim as new, and desire to secure by Letters Patent, is r 1. In a windmill, the combination of a wind-wheel, its shaft and astuh-shaft, a head,

having hearings in line with each other for 2. In a windmill, the combination of a rotar-y head orsupport for a wind-wheel, means fordriving'a pair of chains, a section maint-ained in vertrcally-movable engagementwlth the head, guide-s rockets for the chains vertically-movable section, a pitinau con nected to the chains, a cross hcad pivoted .to i

the pitman, guides for the cross-head attached to the rotary head or support for the mind-wheel and a lower section connected to see,

the intermediate section and resting upon a support, substantially as shown.

3. In a windmill, a head having bearings for the shaft of a wind-wheel and. a stubshaft in line with the shaft of the wind-wheel, bearings for the shafts, means for driving the shafts in unison, sprockets on the adjacent ends of the shafts, a section connected to the head so as to turn therewith and. to be capabio of a vertical movement independent of the head, guide-bars attached to the head. and to the section that is connected to such head, shafts carried by the verticallymiovable section, sprockets on said shafts, chains that engage the sprockets, a itman connected to the chains, eross-hea pivoted to the pitman and provided with a member that 911-. gages the guide-bars and a pump-rod connected to the pitman, substantially as shown.

t. In combination with a wind-wheel and its support, of motion-transmitting mechanism comprising a pair of driven chains, a pitnian connected to both of the chains and to a reciprocating bar, an oscillatory cross-head pivotedto the pitman, guide-bars that are engaged by the head, and a coupling that connects the lower end of the pitnian to the reciprocating bar, substantially as shown.

5. Inawind-wheeh a tubular support, a platform attached to the sup ort and pro vided to one side thereof with an opening, fixtures attached to the support and provided with openings, tubular wheel -supporting sections comprising an upper section orhead 1 that is seated on the upper fixture and extends through the opening thereirna lower section that bears upon the lower fixture and extends upward through the platform, and

an intermediate connectiomsection that is coupled to the upper and lower section, sub

stantially as shown.
